If your business is based in Canada, Australia, New Zealand, Europe, or Hong Kong and you need a US phone number in GoHighLevel, you must complete A2P brand and campaign registration before sending texts. Each country has its own official business registration number, such as the BN for Canada or ABN for Australia, and you must use the correct one to get approved.

Summary. GoHighLevel requires non-US businesses to register their brand and campaign through the Trust Center before using a US phone number for SMS. The process involves purchasing a US number at the sub-account level, locating your country-specific business registration number from the relevant government registry, and submitting your business and contact details for A2P approval. Each country, including Canada, Australia, New Zealand, the EU, and Hong Kong, uses a distinct identifier that must match your official registration exactly.
